Imvelaphi yoShishino: Imingeni yeNdawo yoShishino ukuya kwiValve Handwheels
Kwimveliso yeekhemikhali, imichiza eyohlukeneyo edla ngokutyhutyha rhoqo kwiivalvu, ezifana neklorin kunye ne-caustic soda kwi-chlor{0}}ishishini le-alkali, kunye ne-sulfides ekusulungekiseni i-petroleum, ebeka iimfuno eziphezulu kakhulu kwi-corrosion resistance of handwheels. Kwinkalo yobunjineli baselwandle, -ityuwa ephezulu kunye{3}}nokufuma okuphezulu okusingqongileyo kwamanzi olwandle kuya kubangela ukuthotywa kwe-electrochemical kumavili ezandla entsimbi, okukhokelela ekusebenzeni okucuthiweyo okanye nokusilela kwamavili ezandla. Ngokwezibalo, ukusilela kwezixhobo okubangelwa kukudleka kwamavili eevalvu kubangela iibhiliyoni zeerandi kwilahleko yezoqoqosho kushishino lwehlabathi minyaka le.
Imiba enguNdoqo echaphazela ukusebenza kweAnti{0}}yokudleka kweeHandwheels zeValve eSolid
Iimpawu zezinto eziphathekayo
Isixhobo sisiseko sokumisela ukuchasana{0}} kokusebenza kokutya kwamavili ezandla. Phakathi kwezixhobo zetsimbi, i-carbon steel inexabiso eliphantsi kodwa kulula kakhulu ukurusa. Kwindawo efumileyo, i-carbon steel handwheel engakhuselekanga ingabonisa umhlwa ocacileyo kwi-1{8}}2 iinyanga; insimbi engagqwali inokumelana ne-corrosion elungileyo ngenxa yefilimu ye-passivation eyenziwe ngezinto zechromium. Phakathi kwabo, i-316 insimbi engenasici yenza ngcono kune-304 insimbi engenasici kwindawo ye-ion chloride ngenxa yokongezwa kwezinto ze-molybdenum. Izinto ezingezizo ezentsimbi ezifana ne-polytetrafluoroethylene (PTFE) zinozinzo oluqine kakhulu lweekhemikhali kwaye zinokumelana ne-acids ezomeleleyo kunye ne-alkalis, kodwa amandla abo omatshini aphantsi.
Imiba yokusingqongileyo
Iimeko zokusingqongileyo zinempembelelo ebalulekileyo ekuchaseni{0} ukusebenza komhlwa. Ngokokufuma, xa ukufuma okunxulumeneyo kudlula i-60%, isantya sokutya kwamavili ezandla entsimbi siya kukhawuleza nge-3{6}}amaxesha ama-5. Kwimichiza yeekhemikhali, i-acid oxidizing eqinile (efana ne-concentrated sulfuric acid), i-alkalis eqinile (njengesisombululo se-sodium hydroxide) kunye nezisombululo zetyuwa ziya kutshabalalisa ngokuthe ngqo umphezulu we-handwheel. Utshintsho lobushushu luya kuchaphazela nokusebenza okuchasene nomhlwa. Ukushisa okuphezulu kuya kukhawulezisa ukusabela kweekhemikhali. Uxinzelelo lwe-thermal oluveliswa kukuguquguquka kweqondo lokushisa lunokubangela i-microcracks kumphezulu we-handwheel, inika umjelo wokuthosa.
Inkqubo yokuvelisa
Inkqubo yonyango yomphezulu ichaphazela ngokuthe ngqo i-anti{0}}sakhono sokubola kwevili lesandla. Inkqubo ye-electroplating yenza uluhlu olukhuselayo phezu komhlaba ngokusebenzisa i-chrome plating, i-zinc plating, njl.; inkqubo yokwaleka isebenzisa i-epoxy resin, i-polyurethane kunye nezinye iingubo zokwahlula imithombo yeendaba ezonakalisayo; Itekhnoloji yokutshiza nge-thermal inokwenza{3}}izinto zokuhombisa eziphezulu ezifana neeseramikhi kumphezulu wesinyithi, ziphucule ngokubonakalayo ukusebenza{4}} kokutya.

Ubuchwephesha beFrontier kunye neeNkqubo zoPhucula i-Anti{0}}ukusebenza kokutya
Kwiminyaka yakutsha nje, ishishini belisoloko lijongisisa{0}}itekhnoloji ezintsha zokuchasana nomhlwa. I-Nano{2}}iteknoloji yokugquma iphucula kakhulu ukuxhathisa ukubola ngokwenza ifilimu ye-nano{3}}yenqanaba elikhuselayo kumphezulu; self -ukulungisa iteknoloji yokwambathisa isebenzisa iteknoloji ye-microcapsule ukukhulula ii-agent zokulungisa xa i-coating yonakalisiwe ukulungisa ngokuzenzekelayo indawo eyonakeleyo; Itekhnoloji yemathiriyeli ehlanganisiweyo idibanisa ukomelela okuphezulu kwentsimbi kunye nokumelana nomhlwa kokungeyiyo{5}}zentsimbi ukwenza iimveliso zamavili esandla nokusebenza ngcono.
Ukunikezelwa kweNkcazo eyiyeyona yoVavanyo kunye neZifundo zeMyezo kwi-Anti{0}}iNdlela yokuSebenza kokutya
Inkampani yeekhemikhali ifake i-carbon steel, i-304 insimbi engenasici, kunye namavili angama-316 ensimbi engenasici kwiivalvu zombhobho we-sulfuric acid. Emva kweenyanga ezi-6 zokusebenza, i-carbon steel handwheel yahlwa kwaye ubunzulu be-corrosion yafikelela kwi-0.3mm; I-304 yesandla sentsimbi engenastainless ibonise ukugoba okuncinci kwaye ubunzulu bomhlwa yi-0.05mm; i-316 handwheel yensimbi engenasici yayingenalo utshintsho olucacileyo. Eli tyala libonisa ngokuthe ngqo ukungafani kokusebenza kwamavili ezandla ezenziwe ngezinto ezahlukeneyo kwindawo eyingozi kakhulu.
IiNdlela zokuPhuhliswa koShishino: Imikhomba-ndlela emitsha yeTekhnoloji echasene{0}}nokonakala kwikamva
Kwixesha elizayo, ngophuhliso lobukrelekrele boshishino, uqwalaselo olukrelekrele kunye neenkqubo zokulumkisa kwangethuba ziya kudityaniswa ne-handwheel anti{0}}tekhnoloji ye-corrosion yokubeka iliso kwimo ye-corrosion ye-handwheels ngexesha lokwenyani. Ngaxeshanye, izinto ezichasene -nokonakala kokusingqongileyo kunye neenkqubo ziya kuthi kancinane endaweni yetekhnoloji yemveli{3}}yongcoliseko oluphezulu ukuhlangabezana neemfuno zophuhliso oluzinzileyo. Ukongeza, imigaqo yebhayonikhi iyakusetyenziswa kwakhona kuyilo oluchasayo{5}}kumhlwa, ukulinganisa ukubola{6}}ulwakhiwo oluxhathisayo lwebhayoloji kwindalo kunye nokuphuhlisa imathiriyeli entsha yokuchasana{7}}nomhlwa.
Ukuqukumbela:-Ukusebenza kokuRhakala lilitye leKona eliBalulekileyo loKhuseleko kuShishino
Ukuchasana -nokusebenza kokutya kweIvili Lesandla Esiqinileyongundoqo ekuqinisekiseni ukusebenza ngokuzinzile kwezixhobo zoshishino, ukunciphisa iindleko zokulondoloza, kunye nokuphepha iingozi zokhuseleko. Ngokuqhubeka nokuphucula ukhetho lwemathiriyeli, ukuphuculwa kweenkqubo zokwenziwa, kunye nokuyila ubuchwephesha bokuchasana{1}}nokonakala, ishishini liyakuqhuba liphucula ukusebenza{2}} kokutya kokutya kwamavili ezandla kunye nokwakha umgca wokhuseleko oluluqilima kuphuhliso lwamashishini. Kwixesha elizayo, ngenkqubela phambili yetekhnoloji, ngokuchasene{4}}ukusebenza kokutya kwamavili esandla eevalvu ezomeleleyo kulindeleke ukuba kuphunyezwe impumelelo entsha kunye nokusebenzela ngcono imimandla eyahlukeneyo yemizi-mveliso.
